I am glad you sorted that out.
Since "PureMart" works based on integration to a joomla template, it is impossible for us to take into account all the joomla template styles and the frameworks simply because there are millions differnet joomla templates on the web. You might face some minor CSS issues like you had because of the CSS overriding that caused by your joomla template.
But the "Firebug" plugin will be your number 1 tool to resolve all of them in less than an hour.
For more info and tutorials about Firebug, take a look at this topic:

Case solved. Topic is closed for clearance.
